            <p>HTTP protocol means Web UI and REST APIs. Web UI will ask for the passcode using a specific page. For REST API you have to add the passcode using an HTTP header.</p>
            <p>FTP has no standard way to support two factor authentication, if you enable the FTP support, you have to add the TOTP passcode after the password. For example if your password is "password" and your one time passcode is "123456" you have to use "password123456" as password.</p>
